Altimeter

I-Altimeter uhlelo lokusebenza lwe-Android oluwusizo olukuvumela ukuthi uthole ukuphakama kweqiniso ngaphezu kwezinga lolwandle (MSL) endaweni okuyo manje nanoma iyiphi indawo emhlabeni. Idinga ukufinyelela endaweni yedivayisi yakho ukuze uthole i-altitude eluhlaza ukusuka kusignali ye-GPS futhi ayidingi uxhumano lwenethiwekhi ukuze isebenze. Ukuphakama kweqiniso ngaphezu kwezinga lolwandle kunqunywa kusetshenziswa i-EGM96 Earth Gravitational Model. Izici eziyinhloko yilezi:

• Okungaxhunyiwe ku-inthanethi ukuphakama kweqiniso ngaphezu kolwandle
• Ayikho inethiwekhi edingekayo (isebenza ingaxhunyiwe ku-inthanethi futhi ikumodi yendiza)
• Ukuphakama kweqiniso ngaphezu kwezinga lolwandle (AMSL isebenzisa i-EGM96)
• I-Ordnance Survey National Grid reference system (OSGB36)
• Sebenzisa i-Barometer noma i-GPS Satellite
• Ikheli endaweni yamanje
• Londoloza ukuphakama endaweni
• Ukulinganisa kokunemba kobude
• Ukulinganisa kokunemba okuvundlile
• Ukuphakama kunoma iyiphi indawo
• Khetha indawo kumephu
• Vula ama-geotag esithombe ukuze ubonise ukuphakama okuhlobene
• Sesha indawo ngegama noma ngekheli
• Izixhumanisi ze-Universal Transverse Mercator (UTM)
• Izixhumanisi Zesistimu Yereferensi Yegridi Yamasosha (MGRS)
• Iwijethi yesikrini sasekhaya ukuze ubonise ukuphakama endaweni yamanje

Ukufinyelela kwenethiwekhi kuyadingeka ukuze uthole ukuphakama kwendawo ekhethwe kumephu.

Ubude ngaphezu kwezinga lolwandle (AMSL) ukuphakama (emhlabathini) noma ukuphakama (emoyeni) kwento, uma kuqhathaniswa ne-datum yezinga lolwandle elimaphakathi. Ukuphakama kwe-GPS okujwayelekile kubheka uMhlaba wonke njenge-ellispoid futhi umehluko ofika kumamitha ayi-100 (328 amafidi) ungaba khona phakathi kwalokhu kuphakama kwe-ellipsoid kanye nokuphakama kwe-tidal kweqiniso. Okunye, okuyikhona esikusebenzisa kulolu hlelo lokusebenza, isizindalwazi esime mpo esisekelwe ku-geoid njengemodeli yomhlaba wonke ye-EGM96.

Ukunemba okuqondile kwe-Altitude kuchazwa ngokuzethemba okungu-68%. Ngokucacile, njengohlangothi olu-1 lobubanzi obunamacele angu-2 ngaphezulu nangaphansi kokuphakama okulinganiselwe okubikiwe, lapho kukhona khona amathuba angu-68% okuthola ukuphakama kweqiniso.

Jabulela!
